Quoted from "shaeman" never, ever, ever, ever, ever pug.

Although PuGing will teach you to be a *much* stronger tank and/or healer.
Amen to that. I have had to solo box due to a fund shortage for a month or so now, so I am working on getting my DK tank and holy priest up to lvl 80, and what Fur said about if making you a better tank / healer is right on the mark. If only that was enough to make it worth having tanking gear ninja'd from you...
